IMPROVEMENT IN THlMBLE-SKEINS AND BOXES FOR VEHICLES.

Speciiication forming part of Letters Patent N0. l09,.066, datedNovember S, 1570.

To MZ whom t may concern.-

Be it known that I, THOMAS SMART, Jr., of Brockville, in the county ofLeeds and Dominion of Canada, have invented a new and ImprovedThimble-Skein and Box forWheeled Vehicles; and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the sanne,reference being had to the accompanying drawings, forming part of thisspecification, in which- Figure l represents a longitudinal section ofmy improved thinible-skein, x Fig. 2, being the section-line. Fig. 2 isa vertical transverse section of the same, y y, Fig. l, being thesection-line.

Similar letters of reference indicate corresponding parts.

This invention relates to a new self-lubricati ng axle-box orthimble-skein for wheeled vehicles; and it consists in such aconstruction of the skein and box that the lubricating material will, bythe box, be distributed transversely, and on the skein longitudinally,so as to be thereby brought in contact with every portion of the surfaceto be lubricated.

A in the drawings represents the thimbleskein fitted upon the end of awooden or other axle.

B in the axle'box, held in the hub and revolving around the skein. Theinner end of the box B abuts against a shoulder, a, of the skein, saidshoulder having in its upper part an inclined aperture, b, leading fromthe back to a longitudinal groove, c, on the upper face of the skein.The aperture I) is enlarged at its outer part to constitute a chamber orreservoir for the lubricating material. The

groove c extends from the shoulder a forward, and becomes graduallysmaller toward the outer end in the same proportion as the diameter ofthe skein is reduced, so that 'the supply of lubricating material willthereby be properly regulated. The inner side of the box B contains arecess or enlarged chamber, d, around the superior parts ol' the skein,and in this recess are longitudinal ribs e e. The lubricating materialis poured into the chamber b, which is then properly closed. From thechamber b it flows into the groove c, and along the same to the outerend. Then the groove is filled, the material will overflow to lubricatethe entire circumference ofthe skein. The oil is then collected at thebottom of the box and Hows to the large end of the same, into thechamber d, where it -is taken up by the ribs e and carried again intothe groove, to be used over. In this manner the apparatus will be madeself-lubricating without perceptible waste, as the front joint of theskein and box is closed by a hanged nut, C, which overlaps the end ot'the box, as is clearly shown in Fig. l. Y

Having thus described myinvention, I claim as new and desire to secureby Letters Patent- The combination, with the ordinary oilchannel c, (inan axle-box,) of the'transverse chamber d and longitudinal ribs e,passing therethrough, to take up the superduous oil and gradually conveyit to the end of hub for distribution, as described.
